Application filed February 4, 1922. SerialNc. 534,037.

To all whom it may concern Be it known that we, CAni-uioN'CLIN'roNAxnnnsow and FREDERICK Amine, subjects of Great Britain, residing atWindsor, county of Essex, hrovince of Ontario, Canada, have inventedcertain new and useful lmproiementin Fumigators, and declare thefollowing to be a full, clear, and exact description of the same, suchas will enable others skilled in the art to which it pertains to makeand use the same, reference being had to the accompanying drawings,which form a part of this specificationf Our invention relates tofumigators shown in the accompanying drawings and more particularlydescribed in the following specification and claim. v p

One of theobjccts of this invention is to prove a simple and inexpensiveknockdown fumigator, for disinfection purposes,

it being more especially designed for heat-- ing dry formaldehyde powderto a temperature at which formaldehyde gas is'given off. A furtherobject of the invention is to provid a container for housing dryformaldehyde, the cover for said container serving -when removed fromthe latter a holder or support for the heater or lamp, and also asthesupporting base of the fumigator. .alJlOfhQI feature of the inventionconsists in an annular wall,mounted upon the cover when used as thebase-plate of the fuirigratorfor supporting the formaldehydc containerin spaced relation to a heater or lamp, housed within the annular wall.

Another feature of the invention consists in constructing the annularwall of perforated shcetmetal, or of wire fabric, to insure an evendistribution of the air to the heater in order that perfect combustionand a steady flame, may result, thereby increasing the efficiency of thedevice.

A further object ofthis invention to reduce the fire hazzardbyprotecting, the gas from the naked flame o the lamp or heater,

combustion to pass off in an unobstructed,

A further object is toprovide for-an "un interrupted view of thelamp orheater for the convenience and ready inspection of the operator.

With theforegoing and other objects in view which will: appear as thedescription proceeds the invention further resides in? the combinationand arrangement of parts and in the details of constructionhereinafterdescribed and claimed,--it being understood that changes may be made inthe pre of the same. v

accompanying this spec- Figure 3 is a verticalcross-sectional viewof theformaldehyde container and enclosing case used for protecting the drypowder, the cover serving also as the base-plate of the device when theparts are assembled as in the preceding views.

Figure l is a vertical cross-sectional view of the-heater or lamp withthe cover in place, that shown being of the type com monly known as asolidified alcohol heater.

Referring now to the letters of reference placed upon the drawingsz A,denotes a container for dry formalde ONTARIO,

hyde powder comprising a chamber A fitted with a comprcss1on cover Aformed of sheet metal. The cover A is also employed as the base of thefumigator when the respective parts are assembled, the cover havvingz acentral offset or depression A struckup from the body of the metalto'receive; a lamp or heater. B, denotes the heater which in the presentembodiment is of the type employed to contain solidified alcohol-but anyother suitable lamp or heater may be employed. The heater is fitted withthe usual compression cover B of sheet metal and upon removing which thecontents of the heater may be ignited. C, indicates an annular wall orcollar, mounted upon the upstanding portion of .the base or cover, A forsupporting the formaldehyde shipment.

containersleeved in its upper end-in spaced relation to the heater. Thesupporting Wall or collar .0 is preferably constructed of wire fabric asshown but it may be made of sheet metal perforated for the passage ofair and the products of combustion. It will also be apparent that thewall may be of flat sheet material with means for securing the endstogether to form an an nular wall. Sucha construction lends itself to amore compact form for boxing and Having now mounted upon the base andthe heater B insertedin the central recess of the latter,

the cover of the heater is thenremoved and its contents ignited. Thechamber Acontaining the formaldehyde is then inserted in the upper endof the annular collar or indicated the several parts by referenceletters the construction and 0pwall;-in spaced relation to the heaterwhereupon the heat from the latter will re lease the formaldehyde gas,as may be read 11y understood.

Having thus described our invention what of the body and extending intothe same and supported thereby, a heater of less diameter than the body,and a tapered cover tightly fittingthe container and having a marginalflange, and removable and reversible to form a base for the cylindricalbody and to extend its tapered portion into the same, said cover havinga central depression of a size to receive the heater, and centering thesame. r a

In testimony whereof, we sign this specification in the presence of twowitnesses.
